The loudness of a series of Gaussian pulses and of a series of exponential pulses may be calculated from their amplitude spectrum at any desired level, provided that the repetition rate exceeds 10 c/s and the rise time t e > 0.12 ms. The method of calculation is the same as that developed earlier for the loudness calculation of continuous noise. The loudness of a single pulse is from 2 to 5 phons less, depending on pulse shape, than the loudness of a series of pulses having the same shape and a repetition rate of 10 c/s.

If the rise time t e > C 0.12 ms the subjectively measured loudness is greater than calculated by the above mentioned method. This increased sensitivity of the hearing mechanism for short pulses is also observed when the hearing threshold is artificially altered by the use of random noise.

Finally it is indicated how the loudness of Gaussian pulses and exponential pulses may be estimated if their rise time is less than 0.12 ms.
